Iron is mainly present as iron oxide/hydroxide and ilmenite (Fig. 3). 4.2 Thermodynamic Analysis. In 1973, Bainbridge reported the possibility of achieving selective nickel extraction by gas sulfation, exploiting the difference in sulfate stability between iron and nickel. The same approach can be applied to iron-rich, rare earth ores.
